Current status and applications of hybrid micro-machining processes: A review. (October 2015) - Unune, Deepak Rajendra
The hybrid micro-machining process employs simultaneous or ensuing action of two or more machining processes or takes aid of some energy assistance in material removal to enhance advantages and minimize potential disadvantages found in individual material removal techniques. There are various examples, such as abrasive electro-discharge grinding, electrochemical discharge machining, laser-assisted turning, and jet-assisted machining. This article presents a novel classification of and reviews the past and present research and applications of the hybrid micro-machining process, highlighting its effects on response variables such as material removal rate, tool wear, and surface roughness. Although hybrid micro-machining has been an active research area in non-conventional and critical machining since few years, insufficient knowledge about capabilities in sizes, materials, machinery, and manipulating devices is still a major constraint in the development of these processes. In the near future, there is ample scope for the hybrid micro-machining process in exploring issues in material removal at micro-scale, effect of residual stresses, and environment.
